10 Claims.

, 1 'I'his invention relates to improvements in cartons and particularlyto knocked-down cartons, that is, cartons so manufactured that they arepartially erected and then flattened requiring the user to merely raisethe same from their flattened condition and when the parts are in saidraised position they are secured to one another and which erected cartonis provided With transverse partitions.

Transversely partitioned cartons in and of lthemselves are old and Wellknown, such as used in connection with eggs, bottled goods, and thelike, but these cartons have the partitions formed from extraneousportions or material added to the blank of the carton while thetransverse partitions of the present invention are provided from thesame blank as that from which the carton proper is formed without anyadded-material or added parts. The transversely partitioned carton ofthis invention discloses modifications over and improvements upon thedisclosure in applicants pending application Serial No. 89,891, ledOctober 27, 1949, and the said disclosure in the present application isbased on the general disclosure'in Freel et al. Patent 2,447,243,vissued August 17, 1948.

The principal object of this invention is the provision of a cartonhaving hollow walls with which cooperate flaps to provide transversepartitions for the carton proper.

Another object of this invention is the provision of a foldable orknocked-down carton Which when erected and having the erected partsVsecured in position provides a carton which is equivalent in stabilityand strength to the so 1 called set-up carton and which has transverse'partitions to provide compartments in the carton.

Another object of this invention is the provision of a knocked-down orfoldable carton for accomplishing the foregoing objects and which cartoncan be set up to have transverse partitions supplied from the main panelor 'bottom of the carton and which carton may be set up or erectedwithout the use of a special jig or other set up equipment.

A further object of this invention is the provision of a carton foraccomplishing the foregoing objects that is economical to produce, setup and use.

It is also an object of this invention to provide a knocked-down orfoldable carton formed from a single blank and having transversepartitions with bounding walls that comprise inner and outer Wallmembers and wherein the visible surface of the carton bottom, inner andouter Wall members, and opposite faces of the transverse partitionsexpose the same side of the blank and which side may either have apreferredl finish or a surface impenetrable or resistant to penetrationby grease, liquids, and the like.

Other objects and advantages of the'present invention should 'be readilyapparent by reference to the following specification consideredA inconjunction with the accompanying drawings forming a part thereof and itis to be understood that any modifications maybe made in the exactstructural details there shown and described, Within the scope of theappended claims, Without departing from or exceeding the spirit of theinvention.

Throughout the several views of the drawings similar referencecharacters are employed to dee note-the same or similar parts.

SSeveral modincaticns of the invention lare disclosed in thedrawings'and they will be successively described insofar as they dirferfrom'the modi- -fication illustrated in Figs. 1 to 1, inclusive, whichwill now be vdescribed in detail.

'The blank in -Figgl comprises a main or bottom -pane12ll having itssides dened by score or fold "lines 2|, 22,'23 andd. The score or foldlines 22 and 24 respectively, integrally, hingedlyconnect ifinterchangeably, the term side Wall generally defining the longer of theWalls.

.Since the extensions25 and 2t are substantially identical, it is deemedsu'icient if but one of them be described in detail for ythe both.Accordingly, Yextensicn is provided With a plurality of score or foldlines 29, 3G and 3i lthereby providing, 'between the mainor bottom panelscore line 22 and the end of vthe extension, panels32, 33, 3d and 35. Inthe erected carton the panel 32 forms the side Wall inner Wall memberwhich has its ends defined in part by score or fold lines and 3l and .inpart bycut lines 3B and 3Q ywhich are respectively extensions `of thescore or foldlines 3S and 31. The panel 33 forms in the erected Acartonthe side .wall top Wall member and is of a length greater than thelength of the panel 32 havingr at :its opposite ends inwardly projectingliigs fill and -4| which are defined on their closed portions by the cutlines 33 and 39 of the side Wall panel ."32. 'The Width of the lugs Mland 4I, as will subsequently be made clear, is equal to the end'walls.top wall members and cooperate with said end lWalls top Iwall membersin the final erection of the carton. The panel '3d in the erected4carton forms theside Wall outer wall member and is of .arlengthsubstantially equal tothat ofthe panel 33 .of side wall-top wall memberand the saidpanelisd has its ends defined by score or fold lines l2 and54,3. The-scorefor-fold lines l2 and d3 respectively, integrally,4hingedly connect with the panel '3Q `tucking flaps M and Theremainingpanel 35 in the erected carton 'forms the side vfalls bottom `wallmember and is illustrated as having the ends 'thereof biased orlinclined as -at il ,and M which, however, .is Anot necessary except asit is required in cooperation with the end Walls bottom Wall members aswill subsequently be made clear. The outer edge of the panel 35 isformed by a cut line d8 which provides a plurality of lugs orprojections i9 which in the erected carton form glue or fastening lugsor flaps for securing the carton side Wall outer Wall member inposition. The said glue naps t9 have on their under side, as seen .inFig. l, adhesive, indicated by the reference numeral 58.

The end .vall extensions 2'! and 2t again are substantially identicaland it is deemed sufficient if but one of them be described in detail.Accordingly, extension 2l is provided between the score or fold line 2land the end thereof with a `plurality of score or fold lines 5i, 52 andE53 theresbyproviding, in said extension, panels Sil, 55, 56 and 5l. Inthe erected carton, the panel 554 forms tthe endwall inner Wall memberand is of a length substantially equal to the Width ci the cartonmainorbottom'panel 2t and the panel ilshas its ends deilncd'byscore rorfold lines t and 59. The panel 55,'in'the erected carton, forms the end.wall Aouter wall member and has its ends defined bycut lines and `is,yof Va length greater than `that of :panel 5d to the extent of the sidewalls top wall Amembers 33 Wherefore itbridges the distancelbetweentheside walls outer wall'members orpanels til as will be seen from Figs.3 and 6 and-aswill be :subsequently described. The intermediate panelvforms, in the erected carton, the end .wall `top Wall member and-hasits endsbiasedor'tapered as at @E and iii yalthough this specic formneedinot be Vfollowed Vas the ends of theend wall top Wall member panel '55rests upon the side walls top wall members or panels 33 and bybiasingthese ends a neater vappearance isgiven to the carton thanwould'be the resultif the-corners remained on the said end wall. Theremaining panel 5l i constitutes the end wall bottom wall member and atthe same time provides a glue flap portion to the undersurface oi Whichis supplied adhesive indicated by the reference numeral t2.

The sidewalls :inner Wall members or panels 32 have their ends, asdefined by the score or fold lines 38 and 3l, adjacent to the ends -ofthe end Walls `inner `wall members or panels 54, as dened by the scoreoriold lines 58 and53. fSaid adjacent score or fold lines integrally,hingedly connect with their respective panels corner pieces 12 and 'i3which in the erected lcarton form tucking naps. lThese corner pieceswhen erected form what `is commercially known as bellows corners `andfor which reason they are provided, respectively, with -a rdiagonal foldor score line 'it tand the erection of which will be obvious from Fig.3.

Disposed within the carton main or bottom panel 20 is one or more apsadapted to be disposed norrnalto Ysaid panel and to extend transverselythereof. 'The said flaps may take any suitable or desirable contour,that shown in 'the drawings including arms 63 and Si? each of Whichterminate in a substantially reduced end or blunt 7 point andrespectively indicated by reference r projection of the partitions ends65 and G6 :into

the panels 32 is only for a distance Ito `interlock the parts as willsubsequently be madeA clear.V

Eachof the side walls inner wall members or panels 32 is provided A'with'an elongated aperture 69, there being as many apertures in the sidewalls as there are partitions 61 formed in the carton main or bottompanel 20. It should be here noted that while each ofthe modications inthe drawings shows threepartitions, this number may be increased ordecreased and be Within the spirit of the invention. The side wallsinner wall members apertures 69 may takev any suitable or desirable formthat illustrated in the drawings being preferred as it provides a back'face or shoulder vIll which is'substantially normal to the base 'orbottom panel 20 when the v side walls are erected. The other side of theaperture 69 is shown as vhaving a substantially arcuate contour 1|thereby providing a greater opening at the mid-height of the aperture sothat the end of the partition 61 may more readily insert itself in theaperture upon assembly as will be presently made clear.

After the blank has been out and scored as just described adhesive 5D isapplied to the lugs or naps 49 whereupon the side wall extensions 25 and26 are respectively folded on theirscore line 30 thereby bringing thesaid'adhesive 50 on the glue flaps 49 into engagement with the underside `of the main or bottom panel 20,7that is, that portion of thebottom panel 20 that remains between the openings therein after thepartitions 8 1 are raised to their operative positions. The said lugs 49are illustrated in their attached positions in Fig. 7 wherefore thepartitions are free to be raised in the nal erection of the parts. Theblank is now in the condition as illustrated in solid lines in Fig. 2 inwhich condition it is shipped to the user for storage purposes andsubsequent erection.

The user on desiring to erect the carton does so by upwardly folding theend wall flaps 21 and 28 to be in the position illustrated by flap 21 inFig. 3. The side walls are now raised from their flat folded position tothe positions illustrated in phantom lines in Fig. 2. It is understoodthat the raising of the side walls causes same to fold or bend on scoreor fold lines 22-24, 29, 30 and 3|. In raising the side walls, thebellows corner pieces 12 and 13 were folded to the position illus#trated by the said corner piece 12v in'Fig. 3 and at the same timeprojected the side walls top wall members lugs 40 and 4l behind theupwardly projecting end wall extensions. The tucking flaps 44 and45'-and the bellows corners 12 and 13 are now folded-to be transverselyof the carton whereupon the end walls extensions 21 and 28 aresuccessively folded on their score or fold lines 5I, 52 and 53 to bringthe panel 51 below the undersurface of the mainor bottom panel 20. It isunderstoodv that the adhesive 62 was appli-edto the glue flap portion ofthe panel 51 priorto or during theifolding of the extension so that thesaid adhesive is brought into operative engage'- ment with the bottom ormain panel just inwardly of its end score or fold lines 2 I and 23.

The purpose of and reason for biasing the ends of the side walls bottompanel as illustrated at 46 and 41 is evident from Fig. 7 so as to prenvent the overlapping thereof of the portion of the end wall bottom wallmember or panel 51 'and to bring the glue flap portion of 'said end wallextension panel into engagement' with-.the bottom ormain .panel 20throughout itsleiigth to obtain-,proper adhesive Contact between `theseparts.- .Itis readily. evident that the 'ends-ofthe v and end walls.

sidewalls bottom wall members k35 'may be left pointed and the normallyoverlapping portion of the end walls members panels 51 remev'edaby a outin alignment with the ends of the 'fglue yilap portion of said panel 51or conversely' the ends of the side Walls extensions bottom wall mein-ybers or panels 35 completely removed so that its length is no greaterthan that of the main or bottom panel 20 between the score orjfold lines2land23.

The transverse partitions or flaps 61 Vare now raised from theirhorizontal position'. It willbe understood that the ends 65 and 66 areslightly underlying the inner wall members or'panels 32 wherefore aslight longitudinal bowing of the said partitions or flaps 61 will beeffected -during the upward raising thereof such as illustrated'inphantom lines yin Fig. 5. As soon as; however, the said partition orflap ends are aligned with or register with the side walls inner wallmem-'- bers apertures 69 they spring to their normal position and-theends 65 and 66 are thereby projected into the said openings. 'Thisspringing/or projecting of the said partition ends 65 and 66 ismaterially facilitated by the arcuate side 1I of vsaid `opening oraperture. In 'the iinal position the said transverse partitions restagainst the aperture straight or normal side 10 as' fully illus?- tratedin the drawings. The carton is now in the erected position illustratedin Figs. 4 to lyinclusive, and adapted to receive articles or goods inthe several compartments formedbetween' adjacent partitions andtheoutermost partitions Modications disclosed in Figs. 8. 9 andlldifffer primarily from that in Figs. 1 to 7, linclusive', in that theend walls are of double thickness 'instead of spacedapa'rtor hollowconstruction. A'ccordingly there is eliminated from extensions 21 and28'- the vpanel 55 and its defining score or fold line 52.A` Also thesaid extensions each has its panelV 54', which forms the end wall innerwall member,of a length greater than that in Figg'l. that is, of alength to span the carton substantially between the side wall outer wallmembers, as disclosed in Fig. 11, instead of the side wall inner wallmembers as disclosed in Fig. 3. rlhe said end wall `extensions' 21 and28V' therefore have the panels 56 directly connected through score or4fold line'5 I vwith the panels 54';

:The said modification as illustrated in Fig. 8

has the side Wall extensions 25 and 26' modified by having their panels33', 34' and 35 shortened because of the elimination of the end 4walltop wall members or panels 55. In other words the said panls'35', 34 and33' are made to the'same length as the panel 32 which is to the lengthof the main or bottom "panel between its endscore or foldlines 2l and23. This modication necessitatestherernoval from the panel 33o! the'lugs 40 and 4| and also the removal of "the bellows corner pleces`12 and13;

The blank of Fig. 8 after being out and scored l is folded asillustrated in Fig. 9 forl shipment 4to the user who upon desiring toplace articles .or

jgoods therein follows substantially the samesteps as' above set forthexcept that the side walls are first raised from their folded positionto vbe upfstanding as shown in phantom lines in Figli) whereupon the endwalls extensions,- are raised and Vfoldedo'utwardly on theirrespectiveseore or fold lines'fto enclose the tucking aps 44 and 45 'asabove pointed out. In themodiijca'tion, and

as clearly shown in Figi 11; the raising of the side walls provides ashoulder atthe'ends of the said provided with longitudinal dividingstrips such as shown in Figs. and 11, may have packed there'- incandies, bakery goods, or the like, which may have an exterior poatingor chocolate or soft grease base icings which would penetrate thenormally porous cardboard material from which cartons are generallymade.

The modication illustrated in Figs. 19, 20 and 21 differs from thatillustrated in Figs-151130 18 in that the end walls outer wall membersare formed from panels included in the side walls extensions instead ofthe end walls extensions.

Specifically, each side wall extension has its panel 8| defined by a cutand score lie or a line of perforations 8l which integrally, hingedlyconnects with said ends of the panel 8l a flap 8G which has appliedthereto adhesive 35', applied at the time the adhesive 85 is applied tothe panel 8|.

It will be readily seen that the folding of the sidewall extensions,respectively, on their score or fold lines 39 automatically brings thefiaps into contact with the undersurface of the end walls iiaps or innerwall members 54. The blank of Fig. 19 is now in the folded position ofFig.

20 ready for shipment to the user for erection by him.

It should be noted that the half partition flaps 82 of the blanksfofFigs. 15 and 19 and the end' wall outer Wall members of Fig. 19 arerespectively connected with their adjacent members by cut and scorelines or lines of perforations which are desirable to enable said flapsand panels to make the sharp bends necessary in setting the same up inthe erected cartons.

From the foregoing, it will now be appreciated that there has beenprovided a box or carton for accomplishing the objects initially setforth.
